Improvement in lubricating compounds



UNITED STATES PATENT OFFICE.

JACOB MARSHALL, OF READING, PENNSYLVANIA.

IMPROVEMENT IN LUBRIQATING COMPOUNDS.

To all whom 'it may concern Be it known that I, JACOB MARSHALL, of thecity of Reading, in the county of Berks and State of Pennsylvania, have invented a new and useful Lubricating Compound for Lubrieating Car-Axles and all Kinds of Machinery; and I do hereby declare that the following is a full and exact description thereof, and mode of compounding the same.

This chemical compound consistsin the mixture of water, soap, acetate of zinc, and oil, which ingredients may be mixed in various proportions. I have, however, found the following proportions of the ingredients to answer very well in the manufacture of the lubricating compound,viz: I take one gallon of pure water and dissolve 'therein by heat two drams of white or transparent soap. In another gallon of water I dissolvetwo ounces of acetate of zinc. I then take two gallons of whale-oil, or any other oil of a lubricating quality, mix in it the one gallon of water in which the soap is dissolved, and agitate it well. By this process the oil is mingled and holds in solution the soap. Then I add to this mixture the gallon of water which coutainsthe acetate of zinc, and mixing the ingredients as above I produce a highly lubricating compound, superior to anything of the kind known to me for durability and cheapness. By this process all the lubricating properties contained in the oil are set free, and at the same time impregnated with a metallic substance is imparted by the acetate of zinc.

Some of the materials employed in the abovedescribed compound may be replaced by others possessing similar propertiesas, for instance, different kinds of oils, or soap, or acetates of similar chemical character-so that the compound would notbe essentially changed in its character by such substitutes or replacements. I do not therefore intend to limit myself to the precise ingredients above enumerated, buteontemplate varying both the articles themselves and properties in which they are combined as economy may be necessary or the circumstances may render expedient.

Having thus described the manner in which my lubricator is compounded and used, what I claim therein as new, and desire to secure by Letters Patent, is-- The combination of ingredients herein described. I do not claim the use of soap nor the mixture of soap and oils for a lubricatoi; but what I do claim, and desire to secure by Letters Patent, is-the combination of whale or other oils mixed with the oleate of zinc, prepared by mixing asolution of soap in water with a solution of acetate of zinc in water, in which the oleate of zinc is separated in a saponaceons mass, while the acetate of soda dissolves in the liquid in the manner herein set forth.
